NICU Glossary We Use Many Medical Terms in the NICU. Here Are Some You May Come Across During Your Stay with Us; You Are Always NICU Glossary We use many medical terms in the NICU. Here are some you may come across during your stay with us; you are always welcome to ask questions about anything you hear. Anemia - a low number of red blood cells in the blood. NICU babies are not always able to make red blood cells quickly enough to replace the ones lost when blood is taken from them for testing. Antibiotics - a type of medication used to treat a suspected or actual bacterial infection. Until the specific bacterium is identified, babies receive combination antibiotics to treat them for the most “common” types of infections. Apgar Score - a number given at one and five minutes of age that measures the baby’s condition based on heart rate, breathing, muscle tone, activity level and colour. Apanea – the premature baby has an immature brain, and this means he/she may occasionally forget to breathe. Premature babies may then require stimulation (a gentle rub on the back) to remind them. This is common for premature babies and usually subsides by 34-35 weeks, as their brain matures. Aspirate - breast milk or formula that is left in the baby’s stomach from the previous feeding. Assessing the presence and amount of aspirate helps guide the nurse when deciding whether or not the baby is ready to have his or her feeding volume increased. Aspiration - the direct result of inhaling any foreign matter into the lungs. Bagging - a special way to give babies oxygen and/ or extra breaths using an air filled bag. Bilirubin - a product of the breakdown of red blood cells, filtered out of the blood by the liver. The premature baby’s liver is immature and therefore does not filter as well as it should. This causes the bilirubin to build up in the blood resulting in jaundice (a yellow/ orange hue to the skin). Blood Gas - a sample of blood that measures the level of oxygen, carbon dioxide and acid (pH) in the blood. It is used to measure how well your baby is ventilating and or breathing. Bradycardia (BRADY) - any decrease in the baby’s heart rate below 100 beats per minute that lasts longer than 15 seconds and requires stimulation to correct. It is frequently associated with apnea (see above) and happens less often as the baby matures. CBC (Complete Blood Count) - a blood test done for several reasons, including to determine if an infection may be present and to see whether or not the baby is anemic (see anemia, above). Corrected Age - the age of a baby from the due date, not the birth date. CPAP (Continuous Positive Airway Pressure) – is a type of respiratory support used to deliver constant air pressure into a baby’s nose, which helps the air sacs in the lungs stay open and helps prevent apnea. Cyanosis - dusky, bluish color of the skin, lips, and nail beds caused by having too little oxygen in the blood. Desaturation (DESATS) - when the oxygen level in the blood falls below the set value on the saturation monitor. Acceptable levels of oxygen vary depending upon the baby’s age, and the monitor alarm limits are set accordingly. EBM (Expressed Breastmilk) - milk that mothers express using a breast pump or hand expression. This milk can be used soon after it is pumped, or it can be frozen and saved for later use. Fortifier - human milk fortifier is a powdered substance added to breast milk to give it extra calories and minerals such as calcium and phosphorous. Gestational Age - the number of weeks a woman is pregnant; the age at which a baby is born. Gluclose - a type of sugar in the blood. Different types of glucose monitoring are done but the most common is done using a glucometer at the bedside. Heart Monitor - this monitor shows the heartbeat on a special computer screen. Three gelled electrodes (leads) sit on the baby’s skin. An alarm rings if the readings are not within the normal limits. False alarms are common and usually happen when the baby wiggles or a lead falls off. Hypoglycemia - low blood sugar. Interstitial - refers to an IV that is no longer in the vein and must be restarted. Incubator – a heated and humidified bed specifically for babies in the NICU. The incubator is often referred to by the manufacturer’s name - Drager®. Intravenous (IV) - a small catheter placed a short distance into a vein to provide fluid and or medications. Babies can have IV’s in their scalp, hands, arms, legs, or feet. These sites are rotated regularly. IUGR (Intra-Uterine Growth Restricted) - when a baby’s growth slows or ceases while it is in the uterus. Jaundice (Hyperbilirubinemia) - the yellow color seen in the skin usually during the first 2 weeks of life, due to the buildup of broken down blood cells. Lipids - a white, high calorie fat solution that is delivered by IV or mixed in with your infant’s milk/formula. Low Flow - refers to one of the many ways to deliver oxygen and/or air to babies. Lumbar Puncture - a small needle is placed in the baby’s lower back using sterile technique to get a very small amount of spinal fluid for specialized testing. Lytes (Electrolytes) - the measurement of sodium, potassium, chloride in the baby’s blood. The results of this test help the medical staff treat the baby. Meconium - the first, thick black stools passed by a baby. These stools can last for several days and are thick and tar-like. Murmur - a “whooshing” sound of blood going through the heart and surrounding blood vessels. It is detected by using a stethoscope and listening to the heartbeat on the chest or back. Murmurs are common in premature babies. They can be a sign of a PDA (see below) or other heart problem, or they can be benign. Nasogastric Tube / Orogastric Tube (NGT/OGT) - this tube is placed through the nose or mouth to the stomach and is secured with tape. It is a way to feed the baby and to release built up air and gas in the stomach. Nasal Prongs - small soft plastic prongs that are placed in the baby’s nose to deliver oxygen or air. NEC (Necrotizing Enterocolitis) - a serious bowel condition that can arise unexpectedly in premature infants in the NICU. Babies with it can have bloating, blood in stools, and feeding intolerance; they can become very sick. NPO - nothing by mouth (not feeding). PDA (Patent Ductus Arteriosis) - the ductus is a blood vessel that keeps the blood away from the lungs before a baby is born because the lungs are filled with fluid. Usually the ductus closes shortly after birth. If the ductus stays open (or patent) it may interfere with normal blood flow, heart and lung function. The PDA may be treated with medication or surgery if necessary. For more information, please go to: http://www.sickkids.ca/familyinformation/documents/pda/PDAwebsite.html Phototherapy (Bili Lights) - a special blue light used in the treatment of some types of jaundice. Eye shields are placed over the baby’s eyes to protect them from the light. Pneumothorax - a collection of air in the space between the lung and the chest wall, but outside the lung. Respiratory Distress Syndrome - the most common breathing problem found in premature babies. Because the baby may be too young to have developed an important substance called surfactant, the tiny air sacs in their lungs (alveoli) do not stay open easily, as they should. Without surfactant, the air sacs collapse and the baby cannot get enough air into his lungs to breathe effectively. Surfactant therapy sends surfactant down a tube into the lungs, which helps makes the lungs more flexible and eases ventilation. Oxygen Saturation (SAT) – a term that describes the amount of oxygen in the blood. Saturation (“SAT”) Monitor - a monitor that shows the amount of oxygen in the blood. The small monitor is placed around a baby’s foot or hand/wrist and can be easily identified by the red light. The light does not produce heat. Sepsis - an infection that occurs in the blood. If there is any question that an infection may be developing, blood samples are drawn (culture, CBC) and antibiotics are started. Septic Work-Up - includes blood drawn for CBC, and Blood Culture. If the baby is very ill the medical team may request that spinal fluid or urine be obtained and sent for culture. Spell - a term that also describes a brady, apnea or a desat (see above). Tachycardia - a heart rate that is faster than the average range. The average range for premature babies is 120-160. A full term baby’s heart rate would be slightly lower at 90-140 beats per minute. Tachypnea - a breathing rate that is faster than the average range. Premature babies breathe at an average rate of 40-60 breaths per minute. Full term babies breathe at an average rate of 30-60 breaths per minute. TPN (Total Parenteral Nutrition) - an IV solution (often yellow) that contains nutrients to help a baby grow. TPN is used when a baby is not able, or is just starting to feed. UVC (Umbilical Venous Catheter) - a soft, clear catheter placed into the vein in the umbilical cord. This line is used to give fluids and medications. In very sick or premature babies this line is placed at birth using sterile technique. Vitamin K - helps blood to clot normally; all babies receive one intramuscular injection at birth.

  • What Is the Role of the Placenta—Does It Protect Against Or Is It a Target for Insult?
    Teratology Primer, 3rd Edition www.teratology.org/primer What Is the Role of the Placenta—Does It Protect Against or Is It a Target for Insult? Richard K. Miller University of Rochester School of Medicine & Dentistry Rochester, New York The placenta is not just a barrier but has many functions that are vital to the health of the embryo/fetus. The placenta is the anchor, the conduit, and the controller of pregnancy—and it can also be a target for toxicant action. The placenta encompasses not only the chorioallantoic placenta but all of its extraembryonic membranes (chorion/amnion) and the yolk sac. (Figure 1). The placenta and its membranes secure the embryo and fetus to the decidua (uterine lining) and release a variety of steroid and protein hormones that characterize the physiology of the pregnant female. Figure 1. Placental Structure in the Mouse. Figures depict early development of the mouse conceptus at embryonic days (E3.5, E7.5, E12.5). In the fetus, the visceral yolk sac (vYS) inverts and remains active throughout the entire gestation providing for transfer of selective large molecules, e.g., immunoglobulins IgG and vitamin B12.

  • Equine Placenta – Marvelous Organ and a Lethal Weapon
    Equine placenta – marvelous organ and a lethal weapon Malgorzata Pozor, DVM, PhD, Diplomate ACT Introduction Placenta has been defined as: „an apposition between parent (usually maternal) and fetal tissue in order to establish physiological exchange” (1). Another definition of this important organ was proposed by Steven and Morris: „a device consisting of one or more transport epithelia located between fetal and maternal blood supply” (2). The main function of placenta is to provide an interface between the dam and the the fetus and to allow the metabolic exchange of the the nutrients, oxygen and waste material. The maternal circulation is brought into a close apposition to the fetal circulation, while a separation of these two circulatory systems remain separated (3). A degree and complexity of this „intimate relationship” varies greately between species mostly due to the structural diversity of the extraembryonic membranes of the vertebrates. The early feto-maternal exchange in the equine pregnancy is established as early as on day 22 after fertilization. The fetal and choriovitellin circulations are already present, the capsule ruptures and the allantois is already visible (4). The allantois starts expanding by day 32 and vascularizes approximately 90% of the chorion and fuses with it to form chorioallantois by day 38 of gestation (5). The equine placenta continues increasing its complexity till approximately day 150 of gestation. Equids have epitheliochorial placenta, there are six leyers separating maternal and fetal circulation, and there are no erosion of the luminal, maternal epithelium, like in ruminants (6). Thousands of small chorionic microvilli develop and penetrate into endometrial invaginations.

Endometrium explants were added to cytotrophoblast cell suspensions and placed on an angled gyrating platform in a 37~ incubator. When endometrium was cultured alone it was able to remain viable for up to 3 days. When trophoblasts were cultured alone, they formed small and large aggregates, and occasionally spherical shells with hollow centers. When trophoblasts and endometrium were cultured together, the trophoblasts adhered to the exposed stromal surfaces of the tissue frag- ments. The surface epithelium was not receptive to trophoblast attachment except in one ex- periment when day ~9 endometrium was used for the co-incubation, suggesting that surface attachment is usually restricted. A common finding was the presence of an acellular zone in the endometrium only adjacent to the attached trophoblasts. We speculate that this zone may be caused by proteolysis and resynthesis of ECM proteins by the trophoblasts.

  • Human Development Summary
    Human Development Laboratory Activity Gametogenesis Male The sperm develop within the highly coiled seminiferous tubules of the testes. When the sperm are fully mature they are extremely small, being little more than a bag of genetic material with a tail. The head of the sperm oell contains the nucleus and little else. The tail consists of a flagellum which allows the sperm to swim through the female reproductive tract to the egg. Female The egg is one of the largest cells in the body. As the egg ripens in the ovary it accumulates yolk which will serve as food for the young embryo until the placenta and umbilical cord are fully functional. Egg development is acomplished with the help of special nurse cells called follicle cells. When the egg is fully formed it bursts from the ovary in a process called ovulation. Ovulation is governed by complex nervous and hormonaI controls. After the egg is released from the ovary it enters the oviduct. Embryonic Development Fertilization Fertilization takes place in the fallopian tubes or oviducts. Although thousands of sperm cells may complete the trip to the egg only one will penetrate the cells outermost membrane and fertilize it. From this point on the egg is referred to as a zygote. Cleavage Divisions Almost as soon as the egg is fertilized it begins to divide. First into two cells, then 4, then 8 and so on. These divisions produce a solid clump of 32-64 cells called the morula. Blastocyst The morula continues its trip down the oviduct to the uterus.

Birth asphyxia occurs when a baby doesn't receive enough oxygen before, during or just after birth Hypoxia, hypercapnia, and respiratory and/or metabolic acidemia Fetal Asphyxia Occurrence ACOG reports that fetal asphyxia occurs in 25 of 1000 live births and 15% of those are moderate to severe Assessing Fetal Well-Being Ultrasound Biophysical Profile (BPP) Doppler studies Electronic Fetal Monitor Umbilical Cord Blood Analysis Electronic Fetal Monitor “…a valuable but imperfect tool.” (Clark, et al. 2017, p. 163) Expected Outcomes Decrease incidence of cerebral palsy and intrapartum stillbirth Actual Outcomes No difference # intrapartum stillbirth (one in 300) There were no differences in the incidence of CP Neonatal seizures decreased with EFM Continuous monitoring is associated with a significant increase in C/S and operative births Liability of EFM Year CD% 2015 32.0% 2007 31.8% 1996 20.7% 1988 24.7% 1970 5.5% Benefit Not Realized Unrealistically high expectations Lack of standardization of FHR definitions until 1997/2008 Poor reliability for FHR interpretation Failure to show the validity of FHR monitoring in detecting fetal asphyxia Electronic Fetal Monitor “…of infants born with metabolic acidemia, only approximately one-half could be identified potentially and have delivery expedited, even under ideal circumstances.” (Clark, et al, 2017, p.
